Radiator Analysis - Tech Knowledge
|
This Fluidyne radiator cut-away shows how its internal cooling tubes are designed flat to increase capacity and surface area to aid in efficient cooling. These larger-sized cooling tubes, found on aluminum aftermarket radiators, are less susceptible to corroding and clogging. They use a one- to two-inch or dual one-inch diameter tube (depending on manufacturer specs), compared to a 0.5-inch tube for most OE copper/brass applications. Larger tubing wall thickness helps eliminate ballooning of the core of factory radiators, which is more commonly found on forced induction vehicles experiencing high water pressure.
